ExcBBC
Class Description
Transformer fed static excitation system (static with ABB regulator). This model represents a static excitation system in which a gated thyristor bridge fed by a transformer at the main generator terminals feeds the main generator directly.
Attributes
| Name | Type | Description |
|---|---|---|
| efdmax | PU | Maximum open circuit exciter voltage (<i>Efdmax</i>) (> ExcBBC.efdmin). Typical value = 5. |
| efdmin | PU | Minimum open circuit exciter voltage (<i>Efdmin</i>) (< ExcBBC.efdmax). Typical value = -5. |
| k | PU | Steady state gain (<i>K</i>) (not = 0). Typical value = 300. |
| switch | Boolean | Supplementary signal routing selector (<i>switch</i>). true = <i>Vs</i> connected to 3rd summing point false = <i>Vs</i> connected to 1st summing point (see diagram). Typical value = false. |
| t1 | Seconds | Controller time constant (<i>T1</i>) (>= 0). Typical value = 6. |
| t2 | Seconds | Controller time constant (<i>T2</i>) (>= 0). Typical value = 1. |
| t3 | Seconds | Lead/lag time constant (<i>T3</i>) (>= 0). If = 0, block is bypassed. Typical value = 0,05. |
| t4 | Seconds | Lead/lag time constant (<i>T4</i>) (>= 0). If = 0, block is bypassed. Typical value = 0,01. |
| vrmax | PU | Maximum control element output (<i>Vrmax</i>) (> ExcBBC.vrmin). Typical value = 5. |
| vrmin | PU | Minimum control element output (<i>Vrmin</i>) (< ExcBBC.vrmax). Typical value = -5. |
| xe | PU | Effective excitation transformer reactance (<i>Xe</i>) (>= 0). <i>Xe</i> models the regulation of the transformer/rectifier unit. Typical value = 0,05. |
